Database Architects argues GenDB-V's claimed 22x-61x gains over Umbra and DuckDB come from per-query precomputed auxiliary structures built at load time, not faster query processing. At SF10 the 22 TPC-H queries read ~15GB, and memory bandwidth alone puts a ~280ms floor on a 9950X3D where Umbra runs all queries in ~540ms.
